I uploaded the data. Here are the questions. Please type out the answer because I can't download pdf. Thank youQ6. Assume that the energy lost was entirely due to friction between the ball and the PVC pipe track. For the calculation in this question, you may ignore uncertainties.i. Calculate the total energy lost from your measurements. Show your work.ii.Assume that the total length of the PVC pipe is 1 meter. Use this length and the energy lost (from part i) to compute the average force of friction between the ball and the PVC pipe.iii. Calculate the coefficient of friction between the ball and the PVC pipe.iv. The coefficient of kinetic friction between steel and PVC is 0.38. How does your coefficient of friction compare?
